. GAS-BURNER FOR STOVES OR FIRE-PLACES.

SPECIFICATION forming part of Letters Patent No. 402,177, dated April 30, 1889.

` i Application led August 24, 1888. Serial No. 283,637. (No model.)

To aZZ whom it may concern: l

Be it known that I, TERRENCE MCSWEENEY, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Gas- Burners for Stoves or Fire-Places, of which improvements the following is a specification.

The object of my invention is to vprovide a burner of simple and inexpensive construction, by the employment of which the thor- =,ough admixture of gasand air in proper proportions and the effective combustion thereof maybe attained in stoves or other heating appliances.

To this end my invention, generally stated, consists in a burner-chamber composed of a tubular frame inclosing a central open space,

and having lateral channels or passages leading in opposite directions from a gas and air supply opening to the ends of a passage, in which is formed a llongitudinal series of dis- -charge or burner openings, and in the combi- -a plan or top view of a gas-burner embodying my invention; Fig. 2, a horizontal section through the same at the line of Fig. 3, Fig.` 3, a longitudinal section at the line y y of Fig. 2, and Fig. 4 a transverse section at the line a z of Fig. 2.

In the practice of my invention I provide a burner-chamber, 1, which is cast substantially in the form shown in the drawingsthat is to say, a flattened D-shaped tubular frame, which ,incloses a central open space, 2. A longitudinal air-supply opening, 3, through which the gas-supply pipe also enters the burner-chamber, is formed in the bottom of its rear portion, from the ends of which curved lateral channels or passages 4, formed in the the ends of a longitudinal passage, 5, of smaller transverse sectional area, which is 1n- Vfront of the cover-plate.

closed by the front portion of the chamber, in the upper wall of which is formed a series of discharge or burner openings, 6. The gassupply pipe 7 is connected to a T-piece, 8, passing through the air-supply opening 3, and having its horizontal arms or short extensions 9 secured thereto, extending longitudinally in the rear portion of the chamber in the direction of the adjacent ends of the two lateral channels 4. A cap, l0, perforated by a central opening, is secured upon the outer end of each of the extensions 9, and a diffusing-plate, 11, which is perforated throughout, is connected to each of the caps lO by pins, which hold the diffusing-plate at a short distance from the outer face of the cap. A cover-plate, 12, having a shallow peripheral flange, 13, upon its rear and sides, is secured to the top of the burner-chamber by bolts or rivets passing through lugs I4, formed on the chamber, and projecting into the central open space, 2, the bottom of the flange 13 fitting against the top of the chamber and closing the space 2 at top, except at its front, at which and immediately in rear of the burner-opening 6 there is presented an air-discharge passage, l5, by reason of the absence of the flange from the Fragments of firebrick or other suitable refractory material may, if desired, be placed upon the top of the cover-plate.

In the operation of the burner the gas supplied to the chamber by the' pipe 7 is discharged in opposite directions into the channels 4, drawing in with it a proper supply of air through the opening 3. The gas is subdivided by the perforated diffusing-plates 11,.

and after being thoroughly commingled with the air in the channels 4 is delivered into the opposite ends of the front longitudinal passage, 5, from which the mixture of gas and air escapes, and is ignited at the discharge or burner openings 6. The greater transverse sectional area of the rear and side channels of the burner-chamber affords the requisite volume for the admixture of the gas and air -prior to their discharge, and the delivery to the front passage at both ends thereof effects a more uniform combustion throughout the' IOO which becomes highly heated by the combustion at the burner-openings, imparts heat to the air supplied for supporting combustion through the central space, 2, the same being discharged in a heated condition through the passage 14, immediately above the burneropenings, and aeting effectively to promote combustion thereat.

I claim as my invention and desire to secure by Letters Patent-- 1. The combination of a tubular frame burner-chamber inelosing a central space and having lateral channels leading from opposite sides of a rear gas and air supply opening to opposite ends of a front passage perforated with burner-openings, and a cover-plate which closes the top of the central space at its rear and sides and presents a front discharge-passage for air adjoining the burner-openings, substantially as set forth.

TERRENCE MCSVEENEY.
